containers, to be filled are placed in recesses,

or boxes andthis invention has for its object to provide means whereby bags, or containers, which have not been properly charged are removed from their recesses, or boxes, which removal can be effected without crush ing, or otherwise injuriously affecting the bag, or container, and the invention mainly consists in providing a reciprocating and oscillating carrier, having a plunger and a gripping device, which are adapted to operate to cause a bag, or container, which has not been properly charged to be gripped and removed from its recess, or box.

I will describe this invention with reference to the accompanying drawings which parts in section, a device in accordancewith this invention for removing bags, or containers, which have not been properly charged,

Fig. 1 showing the position of the parts when the bag, or container, has been properly charged, and Fig. 2 showing the position of the parts when the said bag, or container has not been properly charged. Fig. 8 shows in elevation, drawn to a smaller scale than Figs; 1 and 2, the device shown in the said Figs. 1 and 2 and the means for operating it. Fig. 4 is a similar view to Fig. 3 but showing parts in a difierent position. Fig. 5 is an elevation at right angles to Fig. 1. Fig. 6 is a horizontal section taken on the line A. B. F ig. l. Fig. 7 is an elevation of parts shown in Figs. 3 and 4 but with parts in dilierent positions to those shown in the said Figs. 3 and a. 8 is a similar View to Figs. 3 and 4 but showing parts in posi tions difierent from those shown in the said Figs. 3 and 4. The aforesaid Figs. 3, a, 7

member of the and 8 show in progressive stages the position of the parts for effecting the removal of an empty or container, from its recess, or box.

According to this invention 1 provide ap* paratus for filling bags, or containers, with a reciprocating and oscillating carrier 1 (see more particularly Figs. 1 and 2) carrying a plunger 2 and a finger 3, constituting the movable member of a gripping device, the other member of which device is constituted by a pro ection, or stop, 4-, (hereinaftenre ferred to as, the fixed member) on the said plunger 2.

The plunger 2 has a stem 5, slidable inthe carrier 1, provided with a collar 6 upon which bears a coiledspring 7 which acts to yieldably hold the plunger 2 in its normal position beyond the lower end of thecm-rier 1 as shown in Fig. 2. Outward movement of the plunger 2 is nnnted by the collar 6 engaging with a part8 of the carrier 1.

'lhe finger 3, constituting the movable mounted, at 9, on the carrier 1 and is normally held in its closed, or gripping, position by a spring 10 connected at one end to the carrier 1 and at 11 secured to, or formed in one with, the said finger 3, themovement of the finger, 3 under the action of the spring 10, being limited by a stop 12, on the said finger, engaging with a stop 13 on the carrier 1. The'finger 3 is caused to open at the proper times, by an arm lat secured to, or formed in one with, the said finger, which arm is operated by means hereinafter described.

The carrier 1 is so arranged that when the recesses, or boxes, 15, into which the bags, or containers 1G, to be filledare placed, are at rest the plunger 2 on the said carrier is in alinement with the open end of one of the said recesses, orboxes, containing a bag, or container 16, (which bag, or container is, or should be, at this stage, properly charged and itis presumed for the moment that it is properly charged) so that when thecarrier 1 is caused to descend the said. plunger will enter the open end of the said bag, or, cont ainer, and descend therein until it meets the contentswhich arrests any further entry. The carrier 1, however, continues to descend until the finger 3 (which at this stage has been moved to its open position) is brought gripping device, is pivotally its other end to an arm,

into a position,outside the bag, or container, to grip the upper part of one of the sides thereof, but owing to the relative movementof the said carrier with respect to the plunger 2 the active parts of the gripping members 3 and a are moved out of line with each other so that when the finger 3 is moved to its closed position, as shown in Fig. 1, it fails to grip the said side of the bag, or container, between it and the fixed member l and upon the return or ascending movement, of the carrier 1, the properly filled bag, or container, is left in its recess, or box 1-5. If, however, the charging of the bag, or container, 16, has from any cause not been properly effected no arrest of the descending movement of the plunger 2 would be effected and consequently the active parts 01 the gripping members 3 and 4c remain in line with each other, as shown in Figs. 2 and so that when the finger 3 is moved to its closed position as shown in Fig. 4, it grips the upper part of one of the sides of the bag, or container, between it and the fixed member a and upon the return, or ascending movement, of the carrier 1 the empty bag, or container, is withdrawn from its recess, or box, 15 as shown in Fig. 7. The carrier 1 is then turned on its pivot 17 and the movable finger 3 is operated to release the bag, or container 16, as shown in Fig. 8, which then falls clear away of the apparatus.

The carrier 1 may be caused to reciprocate by any suitable means, for example, it may be fixed to, or connected with, any suitable reciprocating part of the apparatus. In Figs. 3, at, 5, 6, 7 and 8 l have shown this as being effected by a piece 18 slidable on a rod 19, to which piece 18 the carrier 1 is connected by the pivot pin 17. The sliding piece 18 is operated, through a connecting rod 20, by a crank 21 secured to a rotating shaft 22.

The oscillation of the carrier 1 may be efi'ected, as shown by way of example in the accompanying drawings, by an arm 23, formed in one with, or secured to, the carrier 1, the free end of which engages, through an anti-friction roller 24:, with a cam-groove 25 formed in a piece 26 secured to the framing 27 of the apparatus;

The finger 3 is moved to its open position to permit of the upper part of the bag, or container, 16, passing between it and its fixed member 4, by an arm 28 of a bell-crank lever which is caused, by a spring 29, to act,

through an anti-friction roller 30, on the arm 11 on the said finger, as shown in Fig. 3; a cam 31, secured to the shaft 22, acts, through an anti-friction roller 32 on the other arm 33 of the said bell-crank lever, to release the arm 14, as shown in Fig. 1, thereby permitting the finger, under the action of its spring 10, to return to its closed position. As the carrier 1 approaches the end of its upward movement the finger 3 is caused to open by the tail of the suitably shaped arm 1 1 engaging with a stationary projection, such, for example, as a roller secured to the cam-piece 26, so that any bag, or container, held by the said finger 3 and the fixed member at is thereby released, as shown in Fig. 8.

it is to be understood that the invention is not restricted to the precise details of construction hereinbefore described and shown in the accompanying drawings, as it is obvious that modifications may be made without departing from the nature of the said invention.
